Dryness: Fatigue lowers the tear flow and causes some eye redness. As long as your vision is not affected or the eyes do not hurt or have pus in them, then you can wait a few days for it to clear. And get some relief from topical lubricant eyedrops. If persistent then see your ophthalmologist.

Dry eyes can be the result of environment (dry air from winter or air conditioning),heavy computer use, medications, general medical problems such as arthritis or aging. The result can be blurry vision or "sandy" feeling in the eyes. Initial relief can be with artificial tears.If symptoms persist, see an ophthalmologist.

Lots of causes: Red eyes can simply be from dry eye syndrome (common in women, especially peri or post menopausal). Other causes include eyelid inflammation (blepharitis) or infection.
Dr. Ilan Cohen
Ophthalmology 25 years experience
Many things: Eyes get bloodshot in response to inflammation. The cause of inflammation can be a huge number of things including infection, dryness, misuse of contanct lenses, allergy etc. There is no way to tell what the cause is unless one examines the eye for evidence of what is causing the inflammation. Consult your eye doctor and avoid over the counter treatments other than lubricating drops.

With fingersticks: If the hands and fingers aren't clean and dry, home blood sugar readings may be inaccurate. Sugar on the fingers could end up falsely elevating blood sugar. A concomitant venous sample in lab could demonstrate a discrepancy. Also, the meter may be inaccurate. Eating before a fasting blood sugar may raise the blood sugar in someone with diabetes because it would not be fasting anymore.

Can l-arginine lower blood pressure & if so what is recommended dosage?

Dr. Ralph Morgan Lewis

Possibly beneficial: In some people. Arginine is converted to nitric oxide, which has a relaxing effect on blood vessels & can thus reduce blood pressure somewhat. No standardized dose has been recommended. Be advised that arginine can also trigger or worsen viral infections like herpes. Discuss this supplement with your doc before taking it.

These days my wife is seeing flashes in one eye occasionally.?

Dr. Andrew Shatz
Ophthalmology 26 years experience
See an eye doctor: Most of the time, flashes of light are related either to floaters (changes to the gel that fills the back of the eye), our less commonly migraines. If the flashes last for more than a day, or if there is a decrease in vision as well, see an eye doctor right away.
